AbstractMorbid obesity results in a restrictive pulmonary syndrome including decreased functional residual capacity. General anaesthesia further decreases functional residual capacity, and consequently alters gas exchanges more profoundly in morbidly obese patients than in nonobese patients. Moreover, these changes persist longer during the postoperative period, rendering obese subjects vulnerable to postoperative respiratory complications. In this review, we present postoperative measures improving respiratory function of these patients. Whether these measures affect outcome remains however unknown. Patients suffering from obstructive sleep apnoea syndrome deserve special considerations that are briefly described. Finally, the algorithm of the postoperative respiratory management of morbid obese patients used in our institution is provided.
